I am simulating people in theater in CFX5.7. Because of the large number, I have to simulate people using subdomain with energy source. Here is my question, suppose one person has a heat load of 100W to space (51W is radiation, the other 49W is convection). In CFX Pre, for the subdomain, should I set the energy source of 49W and radiation source of 51W, or energy source of 100W and radiation scource of 51W?

The reason I am asking is that in manual, it says the radiation source is non-thermal (Is the radiation from people non-thermal?). In the .out file, that radiation source is not involved in the energy balance calculation. Does it mean that radiation do not effect the energy balance?
